What is a flame retardant?

       Flame retardants are a key component in reducing the devastating effects of fire on people, property and the environment. They are added to or handle potentially flammable materials, including textiles and plastics. The term "flame retardant" refers to a function, not a chemical. Various chemicals have different properties and structures. As flame retardants, these chemicals are usually more effective in combination.

What are the most common elements in flame retardants?

       Bromine, phosphorus, nitrogen and chlorine are commonly used as flame retardants. Inorganic compounds are also used in flame retardants either alone or as part of a flame retardant system combined with bromine, phosphorus or nitrogen. It is important to note that flame retardants are not easily interchangeable.

How does a flame retardant work?

       Add flame retardants to different materials or apply them as treatment materials (such as textiles, plastics) to prevent fires, limit the spread of fire and minimize fires. Some flame retardants work effectively by themselves; others act as "synergists" to increase the fire protection effect of other flame retardants. Various flame retardants are necessary because the physical properties and chemical composition of the refractory materials required are very different, so they behave differently during the combustion process. Elements in flame retardants also react differently with fire. Therefore, flame retardants must be properly matched to each type of material. Flame retardants are used to stop or delay fires, but, depending on their chemical composition, they interact at different stages of the fire cycle.

What type of products use flame retardants?

       From hair dryers to laptops and flat-screen TVs, flame retardants are used in products in high-temperature environments. Flame retardants provide consumers with a critical fire barrier and are critical to reducing fire-related risks.

V. Why are flame retardants important?

       Flame retardants are used to prevent ignition by increasing the threshold required for fire; reducing the spread of fire; delaying flash-off, reducing the speed and intensity of burning, and increasing the time for people to escape.

Are all flame retardants the same?

       Flame retardants are not the same and are not interchangeable in terms of fire safety of materials and products. Various flame retardants are necessary because the elements in the flame retardant differ from the fire reaction. In addition, the physical properties and chemical composition of the refractories need to be very different, and they behave differently during the combustion process.

What are the flame retardant grades of plastics?

       Flammability UL94 rating-is the most widely used flammability standard for plastic materials. It is used to evaluate the ability of a material to extinguish after being ignited. There are various methods for judging according to the burning speed, burning time, drip resistance, and whether the dripping beads burn.

Plastic flame retardant grade: from HB, V-2, V-1, V-0, 5VB to 5VA.

HB: The lowest flame retardant grade in the UL94 standard.

V-2, V-1, V-0, 5VB, 5VA flame retardant standards
